IMPROYVEMENT IN SHUTTER-FASTENERS.

The Schedule referred to in these Letters iPaLtent and making part ofthe same.

To all 'whom it may concern Be it known that I, CHARLES K. OsBoaN, of`the town of Dixon, in the county of Lee and State of 111inois, haveinvented a new and useful In'iprovenient in \Vindowblind Fasteners; andI do hereby declare that the; following is a full, clear, and exactdescription of the construction and operation of the same, referencebeing had to the annexed drawing making a part of this specification.

Figure l is a perspective view of a window-frame and blind, showing theapplication of my invention.

Figure 2I is a perspective View of my improved lcdind-fastenerdetachedfrom the blind and windowrame.

Similar letters of reference indicate corresponding parts in the severalfigures of the drawing.

My invention h as for its object to provide an improved devicev foilocking window-blinds in a closed position; and

It consists iu the provision of means for holding the blind-catch up, toprevent its catching upon the window-haine, or in the clothing of theoperator when the blind is open. i

' It consists, also, inthe method of holding the locking-catchestogether, as will-be hereinafter more fully described.

In the accompanying drawing- 4 A isl a window-blind, hinged to the framein the usual manner.

B is an angular arm, pivoted within a metallic cas ing, H, secured tothe inner side of the blind in any convenientmanner.

' Upon the stool of the window-frame a countercatch, C, is secured, intowhich the catch B', formed.

upon the arm B, ts, to hold the blind closed.

Tile counter-catch, withy the catch ,B shutting into it, is placed sofar bach in t-he frame that,vwhen the sash G is closed down upon thestool, it shuts directly over the catch and counter-catch `by means of arecess ont in the bottom rail of the sash, as shown in g. 1, at I).

By this means, the sash holds the two catches together, and prevents theblind from being opened until the sash is raised.

The method ofl fastening blinds closed by placing A' the sash upon thelocking devices is now new, and I do not, therefore, claim it, broadly.

My invention primarily consists in nsertinga spring, I, within thecasing H, immediately under the end of the angulararm B, to hold up saidarm with its catch, as shown in iig. 1, to prevent its dropping downvupon the stool, and interfering with the operation of the blind when thelatter is open. Having thus described my invention,

XV-hat I claim as new, and desire to secure by Let-` 1. llheblind-.fastenen consist-ing of the casing H,

angular arm and catch lB. B', adapted to shut over tho counter-catchC,and the spring I within the casing,
